public void mouseDragged(MouseEvent e) {
Image pieceImage = null;
int x = e.getX();
int y = e.getY();

    if (selectedPiece != "") {
        // Get the image for the selected piece
        switch (selectedPiece) {
            case "K":
                pieceImage = pieceImages[6];
                break;
            case "Q":
                pieceImage = pieceImages[7];
                break;
            case "B":
                pieceImage = pieceImages[10];

        }

    }
    // Draw the selected piece image if there is one
    if (pieceImage != null) {
        Graphics2D g2d = (Graphics2D) getGraphics();
        g2d.drawImage(pieceImage, x - 25, y - 25, 50, 50, null);

What do I mean by that?
Err, instead of painting inside a mouse move event, like you do, instead you would not do that
